Thank you for answering my question.^^
I have been busy because of flight schedules.
So my apologies for late reply.
If a pilot who have foreign license want to fly in us, he/she would go to fsdo? for interview to get temp license.
It will only be approved as private pilot no matter what kinds of license he have, even ATPL.
At that time I had multi eng CPL with IFR.
And than 1 hours of flight with CFR instructor for actual private license approval.
So in conclusion, I flew 50 hours in USA with PPL.
I will try my best to get 1500 hours as fast as I can.
Wish you always have safe and happy flight.
